In the nineteenth century, the awareness of heritage values was basically associated with its monumental value. A century later, the element of social preservation became part of this awareness, while the historic city was better understood in its morphological and typological dimensions. Nowadays, the perception of the values of the historic city has expanded to encompass the symbolic and aesthetic values of places and to a new use of the urban spaces that define the historic city (or site) as a living heritage. Historic places, considered to be urban heritage, are of vital significance for cities today as well as in the future.
